I haven't brewed with Galaxy yet, but I do have a pound in my freezer.
I have not been happy with Equinox at all. I really pick up on the "green pepper" flavor/aroma, even in small amounts. I would advise using it lightly.
For example, I just finished a keg of beer that had 4oz Mosiac/2oz Equinox in the hop stand and 4oz Mosiac/2oz Equinox in the dry hop. The Equinox flavor, surprisingly, completely over powered the Mosiac with it's "green pepper" flavor.
I brewed another beer a couple months ago that was 2:1 Citra/Equinox, and even as strong as Citra is, I still got an unpleasant Equinox flavor/aroma.
With that being said, I made one beer that had Equinox in it that was great. Of the 6oz hopstand only 1 oz was Equinox, the other 5 were all different varieties. The 6 oz dry hop consisted of 1.5oz Equinox, 1.5 oz Amarillo, 1.5oz Mosiac and 1.5oz Citra. That beer was fantastic. Since there was 7 different hop varieties in this beer, it must have had enough going on to hide the "green pepper" flavor/aroma.
Anyways, my advise is use to use very, very little if you're only using two hop varieties. Like, an ounce or ounce-and-a-half for flavoring and and ounce or ounce-and-a-half for the dry hop. Then again, I'm not fond at all of Equinox, so YMMV.
